Additionally, you might try dri first with AGP mode 1x. I saw in the previous
post that Jose is using 4x, which might be a problem, depending on hardware.
I got reboots as well when trying AGP 2x on an ASUS P5A with either G200
or G400 (don't remember anymore). At the moment, I have -current with G400
on ASUS A7M266 and it seems to work fine (played Unreal Tournament for a couple 
of hours in a LAN party, also acting as a server until it crashed). When I find
the time I'll try with the patches on -stable as well.
